ATTACHMENT FOR PIERCING TINS AND DECANTING LIQUIDS.

Specification of Letters Patent.

Patented Dec. 21,1915.

Application filed June 22, 1915. Serial No. 35,718.

T 0 all whom it may concern: Be it known that I, THEODORE MARFILEEHARRISON, a subject of the King of Great Britain and Ireland, and aresident of the post town of Castlemaine, in the county of Talbot, Stateof Victoria, Commonwealth of Australia, have invented a new and usefulImproved Attachment for Piercing Tins and Decanting Liquids, of whichthe following is a specification.

This invention relates to the drawing off of petrol, benzin, kerosene orother liquids from rectangular or other shaped tins, it being necessaryto penetrate the top of a tin in order to decant the contents thereof.

In the past various devices have been used for drawing off liquids fromcontainers of the kind above referred to. Often it has been necessary toemploy a pump, a portion of the tin top being entirely removed to.

admit the pump barrel causing disfigurement to the tin beyond economicalrepair. Further, after piercing the tin top foreign matter hasfrequently entered into the tin through the hole formed and the contentshave often not been strained when decanted. When a pump or the like hasnot been used it has been usual to pierce the tin in two places toprovide a pouring out hole and a vent hole. Generally a quantity of thecontents of a tin is wasted by this method. A certain amount of care andskill has also usually been necessary whether a pump or the like hasbeen employed or not.

The object of this invention is to'provide an attachment or device bythe use of which all waste is avoided as the top of a tin may be readilypierced and a liquid tight joint be formed between the tin and theattachment by a simple movement of the hands. The attachment may also befurnished with a simple but effective strainer, which requires nospecial effort to attach or operate it, and may be folded into acomparatively small compass. Furthermore, it calls for no skill in itsapplication or operation and does not detach any portion of the tin top.A tin may, therefore, be repaired for re-filling at a minimum ofexpense.

Referring to the drawings which form'a part of this specification:Figure 1 is a' part sectional perspective view of this invention, theattachment being shown in its folded state. Fig. 2 is a perspective viewshowing a tin pierced by this invention. The tongue formed is clearlyseen as also a portion of a duplex fastening link. Fig. 3 is aperspective view of this invention the parts being in the positionoccupied when applied to a tin.

The invention includes a tubular spout 2 the length and diameter ofwhich may vary. The inner endof the spout is cut diagonally, the angleof the cut depending upon circumstances. The leading edges of thediagonally cut inner end are sharpened forming a cutting edge 3. Formedthrough the wall of the spout is a series of drain holes indicatedat 4.Outstanding from the spout 2, adjacent the drain holes 4, is a collar 5protruding from which are oppositely situated bosses 6. Formed throughthe bosses and the collar is a hole accommodating a first pivot pin 7the outer ends of which outstand beyond the outer ends of the bosses 6.Resting against the inner surface of the collar 5 is the inner surfaceof a resilient jointing ring or washer 8. This may be formed of 2 rubberor the like and more than one ring may be employed, the thicknessdepending upon circumstances. The outer end .of the spout 2 extends somedistance beyond the collar 5 and may be straight as shown, or bent, orkinked, or of other conformation. Preferably within the outer end of thespout 2 is disposed a strainer 9 of any suitable character. Accommodatedin the outer end of the spout 2 is the shank 10 of a depressor andstopper having a head 11. Secured to the head 11 is the outer end of achain 12 the inner end of which may be secured to any suitable part ofthe attachment. VVithin the spout 2 may be disposed a vent pipe 10*.This is of comparatively small diameter. Its inner end extends to and issecured near the inner end of the spout 2. Its outer end communicateswith a hole, indicated at 11 formed through the wall of the spout 2 nearthe outer end thereof.

With the tubular spout 2 is used a duplex bell crank lever. Thisincludes two minor arms 12 each being integral at its inner end with theinner end of a major arm 13. Formed at the junction of each minor andmajor arm is a first pivot pin hole. Passing into the first pivot pinholes are the outer ends of the first pivot pin 7. The outer ends arespread or overset to retain the pivot pin 7 in position. The outer endsof the major arms 13 are united by a bridge 14. The said major arms mayalso be bent, as at 15. Formed in the outer ends of the minor arms 12are second pivot pin holes. Passing into the second pivot pin holes areinturned opposite second pivot pins 16 each being disposed at the upperend of the leg 17 of a duplex fastening link or yoke. The lower ends ofthe legs 17 of the fastening link are united by a bridge which iscentrally elevated as at 18.

This invention is operated as follows When a tin is to be perforated andits contents poured off the depressor or stopper is placed within theouter end of the tubular spout 2 and the inner end of the spout placedin that corner of the tin from which it is proposed to decant theliquid. The depressor is then forced downward and the cutting edge 3enters the tin. A part circular incision is made and a part circulartongue forced down inwardly into the tin as-indicated at 19 in Fig. 2.The tongue is suspended by a hinging portion, indicated at 20 in thesaid Fig. 2. The tubular spout 2 enters the tin and the jointing ring 8rests upon the tin top. The legs 17 of the fastening link are nowpressed against the tin one each side of the-corner thereof, the bridge18 at the lower ends of the said legs being passed underneath the bottomof the tin. The outer end of the duplex bell crank lever is now liftedand turned or lowered until it restsupon the top of the tin. The bridge18 is thereby strained and the jointing ring 8 pressed upon the tin top.The spout is now locked to the tin and the liquid can be decantedwithout any waste whatever the last of the said liquid passing throughthe drain holes 4. The vent pipe 10'" provides for theadmission of airinto the tin avoiding disfigurement of the same by a vent hole, but itis to be distinctly understood that the said pipe may be dispensed with,if desired, and a small hole he formed in the tin to provide for theadmission of air.

, Having now described my invention what I claim as new and desire tosecure by Letters Patent is Y 1. A decanting attachment, comprising incombination, a decanting tube adapted to be projected through the top ofa tin, means for sealing the opening' through which said tube is proected, a crank lever carried by said tube, and a yoke suspended fromsaid crank lever. for drawing said sealing means into position, saidyoke being adapted to surround the sides and the bottom of the tin.
